The File class provides methods that get and set file creation, modification, and access times. The following code shows how the example uses those methods to get and set a file's times.

// Get the file's times.
private void btnGetTimes_Click(object sender, EventArgs e)
{
    txtCreationTime.Text = File.GetCreationTime(txtFile.Text).ToString();
    txtModifiedTime.Text = File.GetLastWriteTime(txtFile.Text).ToString();
    txtAccessTime.Text = File.GetLastAccessTime(txtFile.Text).ToString();
}

// Set the file's times.
private void btnSetTimes_Click(object sender, EventArgs e)
{
    File.SetCreationTime(txtFile.Text, DateTime.Parse(txtCreationTime.Text));
    File.SetLastWriteTime(txtFile.Text, DateTime.Parse(txtModifiedTime.Text));
    File.SetLastAccessTime(txtFile.Text, DateTime.Parse(txtAccessTime.Text));
}
